Well I figured that this would be the case eventually. If they didn't release as paid DLC it would be like they hated money or something. These DLC packs will probably pull in the most out of the rest of the packages very easily, going to buy the whole set myself right now actually.

Yeah they know where their fan base lies. While the game has a tight control scheme and combat it also has plenty of fan service to go along with it. They need to have plenty of sexy outfits to go with that camera mechanic...
